Corrosion and wear protection of AISI 4140 carbon steel using a laser-modified high-velocity oxygen fuel thermal sprayed coatings
نویسندگان
چکیده
Inconel and micro nano WC-12Co powders were deposited on AISI 4140 carbon steel by high-velocity oxy fuel (HVOF) coating followed laser surface modification. Laser power scan speed varied at different levels. Microstructure microhardness investigated. Nanocoatings performed better than microcoatings. Nanostructured WC powder coatings exhibited greater hardness compared to microstructured coating. When the is increased 170 W, a small cellular dendrite microstructure through multiphase solidification formed due difference in thermal properties of 625 particles. Adequate low preferred produce high-quality From electrochemical corrosion test results, it was observed that rate laser-modified HVOF sprayed lower sample. This shows enhanced resistance substrate material. The porosity percentage higher for all samples when increased.

Thermal Sprayed Coatings Used Against Corrosion and Corrosive Wear
Coatings have historically been developed to provide protection against corrosion and erosion that is to protect the material from chemical and physical interaction with its environment. Corrosion and wear problems are still of great relevance in a wide range of industrial applications and products as they result in the degradation and eventual failure of components and systems both in the proc...
متن کاملCorrosion Protection of Metallic Waste Packages Using Thermal Sprayed Ceramic Coatings
Ceramic coated carbon steel coupons were corrosion tested in water with dissolved salts to simulate exposure to evaporation concentrated groundwater in an underground nuclear repository. Metallography revealed no corrosion at the ceramic metal interface of dense coatings, even though electrical measurements demonstrated that the coatings were slightly porous. Experimental results and a model to...
متن کاملCorrosion Protection of Steel Using Nonanomalous Ni-Zn-P Coatings
A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content ~74 wt % as compared to 15-20 wt % in the conventional plating method! has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO4 , complexing agent and ammonium chloride. V...

The item deals with the possibilities of utilization HVOF coatings in thermal cyclic loading conditions. There were evaluated three types of coatings based on WC-Co, WC-Co-Cr and Cr3C2-25NiCr. The quality of coatings was evaluated in terms of their adhesion as sprayed and also during the cyclic thermal loading, EDX analysis and evaluation of microhardness. Construction and structure of coatings...
متن کاملHydrophobic and superhydrophobic coatings for corrosion protection of steel
Since metals in general, and steels in particular, are vital construction materials in our modern society, the corrosion protection of said materials is of great importance, both to ensure safety and to reduce costs associated to corrosion. Previously, chromium (VI) and other harmful substances were effectively used to provide corrosion protection to steel, but since their use was heavily regul...
